This class is used to send a collection of connection preferences expressed as SMetaData objects between RConnection and Comms server which uses them to construct it stack.

Each tier will look up the preferences it understands, act of them, consume them if applicable (see individual preferences) and pass the rest down to the next tier.

RConnection conn;
User::LeaveIfError(conn.Open(sockSvr));
CleanupClosePushL(conn);

TConnPrefList* prefs = TConnPrefList::NewL();
CleanupStack::PushL(prefs);
TConnAPPref* APPref = TConnAPPref::NewL(aPara->iAp);
CleanupStack::PushL(APPref);
prefs->AppendL(APPref);

error = conn.Start(pref);
